It's never too early to introduce your youngsters to metal, especially thanks to the good folks at Twinkle Twinkle Little Rock Star. In recent years, they've made a habit of taking some of the best works of metal and hard rock audiences and turning those works into lullaby versions for the kiddies and Mastodon are the latest band to get the lullaby treatment.

Roma Music just released Lullaby Versions of Mastodon, giving eight of the band's tracks a sleepy makeover, including "Show Yourself," the current single from the band's Emperor of Sand album. Take a listen in the player provided above. As you can hear, the muscular, catchy riffs are replaced with keys and strings that should send your little one off to dreamtime.

The collection also features lullaby versions of "Curl of the Burl," "Oblivion," "Tread Lightly," "Blood and Thunder," "Sultan's Curse," "High Road" and "The Motherload." If you want to pick up Lullaby Versions of Mastodon, the collection is available via Amazon, iTunes and GooglePlay.

Rest assured, you'd be hard pressed to hear the real Mastodon offering something this sleepy. The band is currently on tour and you can find them playing a mix of festivals and headlining shows. Among those dates is a newly added headlining spot as part of the Psycho Las Vegas lineup. They'll join King Diamond and the Brian Jonestown Massacre as headliners on the Aug. 18-20 festival, which takes place at the Hard Rock Hotel and Casino in Las Vegas.
